HEM FOLDER AND GUlDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 263,054, dated August 22, 1882.

l Application filed June 12, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN MCGREARY, of Cohoes, county of Albany, and State ot New York, have invented new and useful'linprovements in Hem Folder, Gage, and Guide for Knit Undershirts, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

1o My invention relates to that class ot' sewingmachine attachments employed in hemming to guide or fold the goods operated upon and gage the hem.

Hitherto great difficulty has been encountered in forming in a satisfactory manner the broad hem required around thelower extremity ofthe knitted undershirts. With any devices hitherto employed it has been found impracticable to turn under the raw edge with suffizo cient neatness and dispatch and produce by a single operation a neat hem, because of the unequal stretchingof the fabric, the hem produced being awry or puckered and of unequal width in dili'erent parts of its length. So great z5 has been this difculty that manufacturers of knitted goods do not have the raw edge turned under, and instead, after the fold is stitched, have the projecting edges trimmed 0E close to the stitching, to improve the appearance of the 3o work..

The object of my invention is to provide a device which will enable an expert sewingmachine operator to form with rapidity and ease a neat broad hem around the lower ex- 3 5 tremity ot' the knitted nndcrshirt, the said hem Figs. 4 and 5 represent the manner in which my invention is attached to aWillcox & Gibbs sewing-machine.A Figs. 6, 7, 8, andi) illustrate 5o the manner of operating the device. Fig. l() is a modified form of the device.

Like letters in the drawings refer to similar parts ot' the device. f

A is the Ushaped hem folder, gage, and guide, consisting ofthree parts, c, b, and c. The length of the part c determines the width of the hem. O is the knitted garment or undershirt, upon the lower extremity of. which a broad hem, f, is required. lIhe extremity ot' the part a is rounded, as shown in Fig. 3. p

The garment being placed at the left ofthe operator, he draws the edge to be hemmed in under the part a up around the extremity of part a and in toward part b and turns the raw edge under, as shown in Fig. 7. The relative position ot the device A and the presser-foot g, needle h, and feed i is such that when theV machine is in operation and the hem started the goods will be drawn by the feed through the guide and under the presser-foot in such a manner as to bring the stitching near the folded edge.

Figs. 6 and 9 show the manner in which the edge is turned under by the let't hand of the operator. The right hand also assists in the `work of properly guiding the fabric into the device A. The part c assists the operator in keeping the turned edge against the part b. The part c, by bearing against the upper surface of the hem, also contributes to give the hem uniformityin width and otherwise. When the hem has been nearly completed, leaving undone only a short space, as from j to 7c in. Fig. 9, the machine is stopped with the needle down inthe goods, and the operator pushes the incomplete part, swinging it on the needle, out to the right from between the parts ct and c and brings it around under the part a, as shown part c upward or to the right, or in any convenient manner which willv not interfere with the operation ofthe device.

d is a curved prolongation of the part c, terminating above in a slotted plate, e. In Fig. 10, d is a curved prolongation of the part o, terminating in a slotted plate, e', at the right.

B is the upper or shank portion ot' the 11emfolder A, consisting of the parts c, d, and e, the curved part d terminating in the slotted plate e.

rlhe device may be secured to the Willcox 8v Gibbs sewing-machine by a screw, l, passing through the slot ot' part e and into the head ofthe sewing-machine frame, as shown in Figs. 4 and 5, and when so attached to the sewingmachine it can be nicely adjusted in position by turning or moving it about the screw l, or, it' necessary, by slightly altering the form ot' the curved part d.

Having thus described my invention, WhatI claim as new, and desire to secure by Letters Patent, is y l. In a sewing-machine attachment, the herein-described hem folder, gage, and guide A, consisting ofthe parts a, b, and c, madein U shape, and provided with a curved shank terminating in a slotted plate for attachment to the machine, 'substantially as described.

2. The sewing-machine attachment herein described, consistingofan adjustable U-shaped hem folder, gage, and guidehaving the parts a, b, and c, and the curved part d, terminating inthe slotted plate e, substantially as described.

In testimony Whereofl have hereunto set my hand this 8th day ot June, A. D. ,1882.

l JOHN MCGREARY.
